Method Detail

item

public XQArray item(QueryContext qc,
                    InputInfo ii)
             throws QueryException

Description copied from class: Expr

Evaluates the expression and returns the resulting item, or Empty.VALUE if the expression yields an empty sequence. If this method is not implemented, Expr.value(QueryContext) must be implemented instead.

Overrides:

item in class ParseExpr

Parameters:

qc - query context

ii - input info (can be null); required for those Value instances that have no input info)

Returns:

item or Empty.VALUE

Throws:

QueryException - query exception

opt

protected Expr opt(CompileContext cc)

Description copied from class: StandardFunc

Performs function-specific optimizations.

Overrides:

opt in class StandardFunc

Parameters:

cc - compilation context

Returns:

optimized or original expression
